Most definitely.
But she would lose and we would have 4 more years of this national disaster.
Why do you say that? She would unite the right more than any other candidate and that counts for a lot. Palin could bring together Republicans, movement conservatives, Tea Party folks and those disillusioned with the status quo. She is charismatic and could run on a common sense platform. People will have had 4 years of the supposed "intellectual elite" in charge, I think they will take to Palin and her message.
Not saying it will be easy, but I just don't quite get all the "Palin can't win" stuff. Who better than her? High negatives your concern? Even Hillary had them leading in to her primary run and overcame them easily. Yes, she lost, but just barely and in a year much of the left turned on the Clinton(s) in order to get a far more radical liberal elected.
Who out there besides Palin that can not only rally almost all segments of the right, but could fire them up? It's going to take more than a "oh well, he/she is better than Obama" to generate the necessary intensity to actually show up at rallies, phone bank, donate, etc. Seems to me Palin is the natural candidate to take on Hussein and I've yet to see any compelling arguments for why she wouldn't have a good shot at winning.
It isn’t the Right I am worried about...its Independents, esp. Women independents.
